Interpretive Summary: A new garbage processing technology has been developed that sterilizes and separates garbage into a heavy portion (metals and plastics) and a light cellulose pulp called Fluff®. The Fluff portion of this process has the potential to be utilized as a soil amendment to improve soil conditions in highly degraded soils. A study was initiated to evaluate a non-composted Fluff as a soil amendment for establishing native grasses on disturbed Army training lands. The Fluff was incorporated into a sandy loam soil at Fort Benning Military Reservation, GA on two sites: a moderately degraded and a highly degraded soil. The addition of Fluff improved available plant nutrients and soil pH levels at both sites. Also, Fluff reduced soil compaction and increased soil concentration of C and N. Because no adverse environmental effects were detected and Fluff improved soil physical and nutrient conditions as well as improving grass establishment, Fluff could be considered a viable and beneficial alternative to current waste management practices for degraded Army training grounds.

Technical Abstract:
A new garbage processing technology has been developed that sterilizes and separates inorganic and organic components of municipal solid waste. The uncomposted byproduct of this process, Fluff®, has the potential to be utilized as a soil amendment to improve soil conditions in highly degraded soils. A study was initiated to evaluate Fluff as a soil amendment for establishing native grasses on disturbed Army training lands. The Fluff was incorporated into a sandy loam soil at Fort Benning Military Reservation, GA on two sites: a moderately degraded and a highly degraded soil. The Fluff was incorporated at rates of 0, 18, 36, 72, and 143 Mg ha-1 to assess the effects on soil properties for two growing seasons. The addition of Fluff improved available plant nutrients and soil pH levels at both sites. Also, Fluff reduced the level of soil bulk density and increased soil concentration of C and N. Because no adverse environmental effects were detected and Fluff improved soil physical and nutrient conditions as well as improving perennial grass establishment with increasing application rates, land application of Fluff could be considered a viable and beneficial alternative to current waste management practices for degraded Army training grounds.
